7 To all whom it may. concern:

Beit. known that I, WALTER A; SMITH, a citizen of the- United States, residing at Milk Rivenin the Province of Alberta and Dominions, of Canada, have. invented certain new and useful Improvements in: Self-Ex: tinguishing Lamps; and I do ,hereby'declare theffollowing -tocbe:a full; cearyand exact description of. thelinvention, .such as will. en? able others skilled in the art to which-it appertains to make: andluse the same.

This invention relates to -lamps,-.lanterns, and thelike and the primary object-of the invention is to provide an imp-rovedilamprorl lantern, so constructed that ifthesame-I is accidentally tilted or thrown. over thesame will be automatically extinguished, thereby eliminating the possibility of the same exploding or catching fire to articles: :around the same.

Another object of theinventioniis to provide a pair of wings pivotally mounted in theburner cap-oneaclrside of the wick tube and arranged to be thrown over the wick,- bysuitable weights, when the lamp is tilted or i turned over, so as to extinguish the flame.

Another object of the invention is to provide an improved means for engaging one of the wings and extending exteriorly of the burner cap and chimney, so as to manually operate the same, when it is desired to extinguish the lamp or lantern.

A still further object of the invention is to provide an improved device of the above character which is durable and eflicient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at a reasonable cost.

With these and other objects in view the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, forming a part thereof in Which:

VFigure 1 is a side elevation of the lamp constructed in accordance with the invention,

Fig. 2 is a fragmentary side elevation of the same partly in section showing the wings positioned in the burner cap,

Fig.3 is a plan view of the burner cap,

Fig; 4 is a: bottom plan view of the burnercap showing the wicktube in section,=and

Fig. 5 is a detail perspective View of one of the flame "extinguishingwings.

' Referring to the vdrawingin detail where inrsimil'ar reference numerals designate coi responding; parts throughoutthe several views, the numeral 1 generally in dicates the improved. lamp, which includes abowl 2, a burner 3, the cap 4 and the wick tube 5.: The lamp burner and bowl may be of any ordinary 0r preferred constructionas desired Extending through the cap 4 on-each'side ofthe wick tube his a shaftfi, which has its ends journaled as at 7 in the-burner 10. Each of the shafts 6 is bent intermediate its ends to for-mi substantially I Veshaped attaching: portions :8jto which are secured the ex tinguishing wingsifi, whi-ch' are of substantially semi spherical form and have the" shafts 6 i extending through the: terminals; thereof and secured as at 10 to the central portion of P the V shaped sections of the shafts,'to cause synchronous movement therewith. The ends of each of the shafts opposite each other are extended and bent at right angles in opposite directions from each other to provide operating extensions 11, which have secured at the terminals thereof suitable weights '12. The weights 12 are adapted to normally hold the extinguisher wings 9 in inoperative position and out of engagement with the wick, but are so arranged, that in case the lamp is turned over, the weights 12 will gravitate so as to swing the extinguisher wings 9 over the wick and thus extinguish the flame. A manually operating device 13 is provided, for engaging one of the shafts for swinging one of the wings 9 over the wick so as to extinguish the same, when so desired. The manually operating device consists of a lever 14 pivoted intermediate its ends by means of a pivot pin 15 to the edge of the burner L and the lower end thereof is bent angularly to provide an operatin handle 16 whereby the lever is bent inwardly into engagement with the operating arms 11 of the shafts 6 and when it is desired to put out the lamp, the shaft is rocked on its pivot, so as to rotate the shaft lamp extmgulsher wings 9 over the tube.

suitable mechanical device may be connected to the operating lever 15, so that the lamp can be put out at a pre-determined time.

While the improved device has been shown in connection With a lamp it is to be understood that the same can be readily used in connection with a lantern or the like.

It is apparent from the foregoing description, that a lamp or lantern constructed in accordance with my invention will eliminate the possibility of big fires occurring by the tipping over of lamps, such as the Chicago fire, and it will therefore decrease the cost of fire insurance for buildings equipped with lamps of this character.

In practice, I have found. that the form of my invention, illustrated in the accompany-. ing drawings and referred to in the above description, as the preferred embodiments, is the most efiicient and practical; yet realizing the conditions concurrent with the adoption of my device will'necessarily vary, I desire, to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sac-1 rificing any of the advantages of my invention as set forth. What I claim as new is:

1. In a device of the class described, the combination, a lamp including a burner tube and cap, of pivoted wings arranged in the cap on each side of the burner tube, shafts journaled to the burner cap on each side of Copies of this patent may be obtained for directions,

the wick tube, said wings being secured thereto, and weights secured to the opposite ends of the shaft.

2. In a device of the class described, the combination, of a lamp including a wick tube and burner cap, of a shaft extending across the burner cap oneach side of the wick tube and having its terminals journaled in' the burner cap, and arcuate wings secured to each of the shafts, the opposite ends of the shafts being bent angularly in opposite and a weight secured to the terminals of the angular ends of the shafts, as and for the purpose specified.

3. In a device of the class combination, of a lamp including a burner tube and cap, of a shaft extending across the burner cap on each side ofthe Wick tube,

-an arcuate wing carried by each shaft, the

opposite ends of the shafts having angular operating portions formed thereon, a'weight secured to the terminals of the angular portions and an operating lever extending exteriorl of the burner cap and engaging one of the angular ends of the shafts for manually operating the same, as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
